Hey guys,

I bought a new monitor for my semi-gaming setup - BenQ XL2430t. It's a 144Hz screen that has all sorta cool configurations. I've connected it to my MSI 970 GTX (overclocked) with a DisplayPort cable (from both sides), booted, and... err. Well, PC powers on, doesn't post (or posts briefly, not sure), then shuts down. I tried it several times and it still happened. On a separate occasion for a reason beyond me I managed to boot it with the DP and everything worked, except when I shut it down the bootloop returned.

Now, if I take out the display port and connect the monitor via DVI - everything works perfect.

I've googled it and it turns out that this is a common problem that happens because 20 pin DP cables have some feedback voltage back into the GPU which messes it up - Though it sounds really weird in my opinion, I mean, those cables are available worldwide and people don't complain :confused:

So my questions are:
1. Has anyone ever run into this problem? Were you able to fix it?
2. Say I ignore this issue, do I lose anything if I use the DVI instead of the Display port? I'm playing at 1080p 144Hz.
3. How the hell can a monitor affect boot :shock:

If the cable isn't new, I would buy a new one first. The Amazon Basics ones are low cost and good quality.
